The most important cytologic criteria with MTC's FNA/FNB are a dispersed cell pattern of polygonal or triangular cells, azurophilic cytoplasmic granules, and extremely eccentrically placed nuclei with coarsely granular chromatin and amyloid [7]. High calcitonin can be used in conjunction with FNA/FNB for the diagnosis. Here, CALCA is linked to medullary thyroid gland carcinoma.
